Hello again, it's the guy who was behind orchestrating last year's Undertale photoshoot.

A small stipulation this year to help stop confusing situations from happening this year.
If you are doing a human version of any of the monster characters, such as say Papyrus or Sans, do at least try to follow the costume themes in the game, or have a prop to help identify your character, if you are a human Papyrus cosplayer with just an orange hoodie, no one will know who you are.

An example would be to do the scarf, or if you are ambitious, try to make the armor, or at the very least the shoulder pads.
